When used in conjunction with a riser sleeve, it has high strength and good refractory properties, with a wide range of specifications; the riser sleeve can be removed by hammering, reducing the workload for cleaning and grinding; it avoids the cracks and defects such as chipping that occur when removing the riser sleeve by gas cutting, reduces the thermal joint at the base of the riser sleeve, and helps improve the mechanical properties of the casting.
